Just like creating your own color grades from scratch, Photon offers you the ability to import, inspect and edit existing 3D lookup tables using all of the tools and range controls we learned about in the previous articles. 

To help you get started, Photon automatically imports compatible LUTs from your installations of Adobe Photoshop and Davinci Resolve. Just like importing preview image folders into your media library, you can import entire LUT folders.

Editing LUTs

In the demo video below we're making some simple adjustments to a film emulation LUT by Adobe:

Tip: You can almost instantly improve the quality of many existing LUTs by importing them into Photon and simply increasing their color smoothness by playing with the "Smoothing" control at the top right hand side of the color shaper panel.

Just like your own grades, you can change the intensity of any imported LUT by playing with the "Intensity" control. This control can also help you understand the 3D transform directions of a LUT by looking at the 3D color cloud inside of the Spindle updating in real time as you change the intensity. 

Importing LUTs without replacing your current grade

Photon allows you to import LUTs as Snapshots. Snapshots are usually used to create memories of different stages of your grades which can be merged and even mixed back into your main grade later. 

You can import LUTs as snapshots by clicking on the plus (+) icon on a selected LUT in the LUT library:

Clicking on the + icon of a selected LUT will import it as a snapshot item
Clicking on the + icon of a selected LUT will import it as a snapshot item

Now the LUT will be visible in the snapshot list at the bottom of the color shaper panel:

You can toggle between the "Current Grade" and any snapshots by selecting a snapshot item from the list.

Mixing LUTs into your grade

As mentioned previously, snapshots allow you not only to easily jump through different iterations of your grade, they can also be mixed into the current grade. 

By default, when you select a Snapshot from the list, it will be previewed at 100% intensity. You can change the intensity by which the snapshot is mixed with the current grade by dragging the intensity control directly on the selected snapshot item.

Mix snapshots into your current grade by changing the intensity before confirming the merge.
Mix snapshots into your current grade by changing the intensity before confirming the merge.

Click on the checkmark icon or hit enter on your keyboard to confirm. The snapshot will be merged into the current grade at the selected intensity.

You can exploit this mechanism to mix all sorts of LUTs into each other and combine them with different versions of your grades at various intensities. You can at any point create a new snapshot of any combination you have created.
